Cache downloaded translations

[MrHaroldA]

Every time composer drupal:l10n is called, it downloads the exact same translation files from drupal.org. This is a waste of bandwidth and time, especially on larger projects.

Is there a way to cache these downloads?

Hello,

Thanks for the suggestion.

I don't know the API of Composer cache, but maybe it can be used, but it will require to be able to check the timestamp of the downloaded files to be sure to have the last up-to-date versions.
